Short for Practical Extraction and Reporting Language, Perl is an
interpreted programming language
first developed by Larry Wall in 1987
that is similar to
the C language. Perl is one of the more commonly used languages in
writing CGI scripts and programming for Internet
and web page applications. Below is an example of a Perl script that
prints "Hello World!".
|
#!/usr/bin/perl
print "Hello
World!\n";
|
Files that include Perl code on a web
server may have any type of file
extension; however, they
commonly end in .CGI, .PL, or .PLX.
Perl is a free and
open
source
programming
language
available for numerous different operating systems. If you're running
a Linux
distro, often Perl will already be installed on the computer.
However, users
running MacOS or
Windows
will need to
download
and install.
We recommend users try the free download for
ActiveState
